How is Siddiqui, the head of the Urdu Department, symbolic of past grandeur in In Custody?

The head of the Urdu department at the college where Deven teaches, Siddiqui is a slim, refined bachelor who lives in his family's ancestral home, a sprawling but decrepit manor. He lioves in the crumbling grandeur of the past. He often pretends that the past is still the present. He loves songs, dance, drink, and gambling; at one point, Deven marvels that off-campus, he is a "sybarite" (136). He is initially supportive of Deven's project, but he grows impatient with Deven's problems and failures and tries to extricate himself.
